1.1 Important Information

Potentially dangerous gas in device

1.2 Intended use

1.2.1 Purpose of the device

MERCEM300Z and MERCEM300Z Indoor (referred to as "device" in the following) are

extractive gas analysis systems and serve continuous measurement of mercury and

mercury compounds in the exhaust gases of industrial combustion plants (emission

measuring system).

The sample gas is taken at a sampling point and fed through the gas analysis system

(extractive measurement).

1.3 Product identification

Type plates

Number of type plates: 2

Position: Top right, inside and outside.

NOTICE: During measurement: Keep cabinet door closed

An open cabinet door results in measurement errors.



Keep the cabinet door closed during operation.

WARNING: Risk to health through contact with toxic gases

The modules and devices contain enclosed potentially dangerous gases that

can escape due to a defect or leak. Refer to the Table below for these gases.

If a leak occurs, the concentrations inside the enclosed device can increase up

to a certain concentration. These concentrations are also shown in the Table.



Regularly check the state of the device/module seals.



Only open the device when well ventilated, especially when a leak of a

device component is suspected.

2.2.1 Method of operation

The device operates independently.

The operating states are signaled by status signals and entered in a logbook (SOPAS ET



p. 19, §2.6).

● Feeding of the sample gas to the analyzer in a heated sample gas line.

● Conversion of mercury compounds into elementary mercury in a thermal converter.

● Measuring principle: Photometric with Zeeman effect.

● Standardized (pressure, temperature) output of measured values.

● Output, relative to humid flue gas.

● Test gas feed (adjustment)

● Integrated adjustment cell for automatic adjustment without test gases (



p. 44, §5.4.3).

● Operation with external UPS (uninterruptible power supply) (



p. 69, §8.5) possible.

2.2.2 Test gas generator CALSIC300 (option)

Option: Integrated test gas generator CALSIC300 (position



p. 15, Fig. 3).

● The initial solution, an HgCl

2

solution, is in a storage container (position



p. 15, Fig. 3).

● Using a vaporizer, the test gas generator generates test gas from the HgCl

2

solution.

● The test gas is transported to the cell via the gas sampling system (“test gas feeding on

gas sampling system”) (



p. 16, Fig. 4 and



p. 26, §3.5.3).

● The test gas concentrations of the test gas generator are set using a menu.

● Test gas feeding is started cyclically or manually (



p. 41, §5.4).

2.2.3 Instrument air conditioning (option)

Option: Integrated instrument air conditioning.

Menu item Test gas feed ... Reference

2.3 Operation

● The unit is operated via an operator panel in the front door of the device.

● The device signals an uncertain operating state with status indicators (



p. 33, §4.3).

The device remains in Measuring mode.

● Should a malfunction occur, the device switches automatically to “Stand-By” (



p. 68,

§8.4).

– The sample gas line and the sample gas path in the device are automatically purged

with instrument air in this mode.

If a test gas generator CALSIC300 is used: Test gas generator and vaporizer are also

purged.

– The analog outputs remain at the last valid measured value.

2.3.1 Operation via SOPAS ET (option)

Operator menus and measured value displays are also available on an external PC via the

Ethernet connection (with the SOPAS ET engineering tool



p. 19, §2.6).

2.4 Interfaces

● 2 x analog outputs

● 4 x digital inputs

● 4 x digital outputs

● 1 x Ethernet interface

More interfaces depending on configuration (refer to “Documentation of individual set-

tings”).

2.5 Remote control

2.5.1 Ethernet

Standard: Ethernet (Modbus TCP/IP).

2.5.2 Modbus

Modbus

®

is a communication standard for digital controls to connect a »Master« device

with several »Slave« devices. The Modbus protocol defines the communication commands

only but not their electronic transfer; therefore it can be used with different digital inter-

faces (Ethernet).

2.5.3 OPC (option)

OPC is a standardized software interface that allows to exchange data between the appli-

cations of different manufacturers.

The SICK OPC server is required.

System bus: Ethernet.

2.6 SOPAS ET (PC program)

SOPAS ET can also be used to set the device parameters and provides access to the log-

book.

SOPAS ET runs on an external PC connected to the device via the Ethernet interface

(



p. 29, §3.7).

2.6.1 Language

Language setting exclusively in SOPAS ET:

Menu: Diagnosis/System info (User level: Authorized operator).

Then change once to any menu on the operator panel.
